What Jaywalk3r said is indeed true. Spinal discs are gel-like materials in your spine that makes it bendable and flexible. They act like shock absorbers for your spine whenever you're running around, biking, jumping up and down or whatever. Without these flexible discs in your back you wouldn't be able to walk around or do much of anything.
